This may seem like a stupid question, but the Mobile Wi-Fi Hotspot products will work ANYWHERE?
For example, if I brought one into the wilderness, the Wi-Fi I'd get in the middle of nowhere would be just as good as the Wi-Fi I'd get in my house? Assume I have a great, high-speed connection at my house.
That would be correct, it will allow you to connect up to 10 devices and will work just like your home router, but whether you have service that is a different story, consult the sprint 4g map https://coverage.sprint.com
